<TD COLSPAN="5">* The numeric keypad mode determines whether <SPAN CLASS="keyname">RETURN</SPAN> and <SPAN CLASS="keyname">ENTER</SPAN> generate the same control codes. The
codes generated by <SPAN CLASS="keyname">RETURN</SPAN> are changed by two feature selections:
<UL>
<LI><P>The auto turnaround SET-UP feature when using half-duplex coded control (HDX B). The turnaround/disconnect
SET-UP feature selected the turnaround character. If the turnaround character is carriage
return (CR), the terminal transmits only one CR when you press <SPAN CLASS="keyname">RETURN</SPAN>.</P></LI>
<LI><P>The line feed/new line feature. When this feature is on, <SPAN CLASS="keyname">RETURN</SPAN> generates two characters (CR, LF). When
this feature is off, <SPAN CLASS="keyname">RETURN</SPAN> generates a CR.</P></LI>
